RELATED ART

Currently, interest in the use of a wearable device is increasing. Such a wearable device refers to a device that is fabricated to be wearable around a body or on top of clothes of a user. For example, a wearable device may include an electronic device that is fastened to a user by a band, strap, or other form of attachment. Such a wearable device incorporates miniaturization and weight lightening technologies. By using small, light wearable devices, such devices are highly portable. Because of the portability, a user may use the device at the user's convenience in a mobile environment.

Accordingly, the wearable device may be present with the user at all times even though the user is participating into a predetermined activity, such as a physical activity, and may be used by the user at all times during such an activity. Each time the wearable device is used, the wearable device may provide information to the user by implementing an instruction. For example, the instruction may be received from the user or from another source, such as another device, which may or may not also be a wearable device. Various types of wearable devices, such as a wearable device for clothes and a wearable device for accessories, for example, may be used. In these contexts, the wearable device may be contained in or attached to the clothes or the accessories. Further, the wearable device described above is potentially usable in a variety of fields, such as a fashion and a medical field, for example. However, these are only examples and potential application fields. The variety of uses of the wearable device is likely to be even broader in the future.

FIG. 1 illustrates an example of a communication method using a wearable device, according to an embodiment.

Referring to FIG. 1, in operation 110, the method recognizes a gesture of a user by sensing a motion and a biosignal that occur in or around a portion of the user's body to which the wearable device is attached. In this embodiment, the wearable device is attached to a portion of a body of the user. For example, a wrist-type wearable device is attached to a wrist of the user, and a glasses-type wearable device is attached to a head of the user. In these examples, a wrist-type wearable device may be attached to a wrist of the user by a band that fastens the device to the wrist of the user, or the glasses-type wearable device may be attached to head of the user using traditional frames that hold the device in front of the eyes of a user by resting lenses on the bridge of the user's nose and anchoring the lenses on the user's ears. However, these are only examples and wearable devices may be situated in other places and supported in other places as well.

In embodiments, the user moves a region corresponding to or surrounding the portion to which the wearable device is attached. For example, in the case of a wrist type wearable device, the user may move his or her hand, wrist, fingers, arms, or even torso. Such movement leads to the movement of wearable device. As another example, in the case of a glasses-type wearable device, the user may move his or her neck or facial muscles. However, in the case of a glasses-type wearable device, an embodiment may track the movement of the user's eyes, even though the glasses-type wearable device is likely not in direct contact with the glasses. Tracking the movement of the user's eyes may be featured in such an embodiment because it may provide information that allows the wearable device to provide a more effective interface to the user.

A biosignal may occur in or around the portion of the user to which the wearable device is attached. In operation 110, the motion and/or the biosignal occurring in or around the portion where the wearable device is attached are sensed. By sensing the motion and/or the biosignal, the embodiment is able to gather data about the user that it interprets to infer what the user would like the wearable device to do.

In an embodiment, the wearable device includes a motion sensing device and/or a biosignal sensing device. The motion sensing device senses a motion occurring in or around an attachment portion. For example, the motion sensor includes at least one of an acceleration sensor, a gyro sensor, and a camera. By using such sensors, the motion sensing device is able to gather information that characterizes the motion of the user.

Similarly, the biosignal sensing device senses a biosignal occurring in or around the attachment portion. In an embodiment, the biosignal sensing device includes at least one of an electromyogram (EMG) sensor, an electrocardiogram (ECG) sensor, an electroencephalogram (EEG) sensor, and a temperature sensor. Such sensors measure electrical signals or thermal energy that provides information about the physiology and biological activity of a user. Accordingly, in operation 110, the motion of body parts of the user occurring in or around the portion of the user to which the wearable device is attached is sensed using the motion sensing device, and the biosignal occurring in or around the portion of the user to which the wearable device is attached is sensed using the biosignal sensing device. In an embodiment, after such information is gathered, a gesture input from the user is recognized based on the sensed motion and biosignal. For example, the recognized gesture input indicates an action the user would like the wearable device to take, or another instruction or input from the user to the wearable device.

For example, in a case in which the wearable device is provided as a wrist-type wearable device, a motion of a wrist or an arm is sensed using at least one of an acceleration sensor and a gyro sensor, and an EMG signal according to a muscular contraction or relaxation of the wrist is sensed using an EMG sensor in operation 110. By analyzing information provided by these sensors, an embodiment is able to infer characteristics of how the user moves his or her wrist. For example, when the user turns his or her wrist clockwise or counterclockwise, an acceleration speed at which the wrist moves is sensed using the acceleration sensor, an angular velocity at which the wrist turns is sensed using the gyro sensor, and an EMG signal of contracted and relaxed muscles among the muscles of the wrist is sensed using the EMG sensor. A gesture of the user turning the wrist clockwise or counterclockwise is recognized based on the sensed acceleration speed, angular velocity, and EMG signal. As will be discussed further, recognized gestures are interpreted by the wearable device as inputs and/or commands from the user to the wearable device.

As another example, in a case in which the wearable device is provided as a glasses-type wearable device, the user may move his or her head up and down. In this example, in operation 110, a motion of the head is sensed using a camera built into or attached to the glasses-type wearable device. In this example, additionally, brainwaves of the user are sensed using an EEG sensor. Such an EEG sensor may be included in the glasses-type wearable device or attached to the user in a way to monitor electrical signals that are representative of the brain activity of the user. Accordingly, in an example where the wearable device is a glasses-type device, a gesture of the user is recognized based on the sensed motion of the head and brainwaves of the user.

As another example, the wearable device is provided as a clothes-type wearable device, such that the wearable device is attached to user at some location on the outside or inside of the user's clothing For example, for such a clothes-type wearable device, a motion of the user is sensed using at least one of an acceleration sensor and a gyro sensor, and an ECG signal according to the motion of the user is sensed using an ECG sensor or the temperature of a portion moved by the user may be sensed using a temperature sensor in operation 110. Because the ECG signal provides information about the cardiovascular system of the user and because the temperature sensor provides information about the body temperature of the user, these sensors provide information about the physiology of the user as a biosignal that is monitored by the wearable device. Accordingly, for a clothes-type wearable device, a gesture of the user is recognized based on a biosignal, such as the ECG signal and the body temperature, and the sensed motion of the user.

Further, in operation 110, in an embodiment, whether a gesture is input from an authorized user is verified based on a biosignal. As discussed above, various sensors receive information about a biosignal associated with a user. For example, a specific user may be associated with a particular EEG or ECG signal pattern. The embodiment analyzes the biosignal generated by the user. If the biosignal matches the characteristics of an authorized user, the authorized user is authenticated, and if there is no match, then no authentication occurs.

When the user is authenticated, the gesture is recognized by sensing the motion and the biosignal. Conversely, when the user is not authenticated, the input gesture is not recognized. Performing such an authentication operation helps ensure that only a user who is entitled to use the wearable device is allowed to do so. Since each user has a different biosignal with different, recognizable characteristics, in an embodiment the communication method using the wearable device is performed only in a case in which an authorized user wears the wearable device. However, the authentication is optional, and in another embodiment a gesture from any user is recognized, irrespective of whether or not the user is an authorized user.

For example, in a case in which the wearable device is provided as the wrist-type wearable device, a thickness of a wrist of a user wearing the wearable device is sensed using an EMG sensor or another type of sensor that measures wrist thickness included in the wearable device in operation 110. In this example, information associated with the wrist thickness of an authorized user is stored in the wearable device before the user attempts to use the wearable device, and the stored wrist thickness and the sensed wrist thickness may be compared.

When the stored wrist thickness and the sensed wrist thickness match, the user wearing the wearable device is determined to be an authorized user. The stored wrist thickness and the sensed wrist thickness may be determined to match if they are the same, or may be determined to match if the difference between the stored wrist thickness and the sensed wrist thickness are within a predetermined difference from one another. Subsequently a gesture of the user may be recognized by sensing a motion and a biosignal because the wrist thicknesses indicate that the user is an authorized user. Conversely, when the stored wrist thickness and the sensed wrist thickness do not match, the user is determined not to be an authorized user and the gesture of the user is recognized.

In operation 120, the method recognizes an external device that is to perform wireless communication with the wearable device. For example, the external device refers to a device where the user of the wearable device does not have unlimited access privileges. In an embodiment, the user of the wearable device interacts with such an external device, but the interaction is limited and/or controlled. For example, the external device may include a smart device, such as a smart phone, of another user, a wearable device of the other user, a wireless fidelity (WiFi) router, and a payment device. The external device may include a near field communication (NFC) device, for example, a smart device to which NFC is applied, capable of performing NFC with the wearable device. However, these examples are not intended to be limiting examples, and other embodiments use other types of external devices. External devices may use a variety of wireless communications technology and protocols, such as Wi-Fi, cellular technologies such as 3G and 4G technologies, and short-range wireless technologies such as Bluetooth and NFC.

In operation 120, in an embodiment, the wearable device is set to perform the wireless communication with the external device, and is also set to perform the wireless communication with the external device based on the recognized gesture. Also, at least one external device to perform the wireless communication is discovered and the external device to perform the wireless communication with the wearable device is selected from among the at least one external device identified in the discovery process. The external device to perform the wireless communication with the wearable device may be selected from among the found at least one external device based on the recognized gesture. Thus, as will be discussed further, different recognized gestures may invoke different interactions between the wearable device and various external devices.

Although operations 110 and 120 are illustrated as being sequentially performed in FIG. 1, operations 110 and 120 may also be simultaneously performed. Operation 120 is further described in FIG. 2.

In operation 130, the method establishes wireless communication connection with at least one of the external device and the internal device based on the recognized gesture. The internal device may refer to a device that the user of the wearable device has full control over. For example, the internal device may include a smart device owned by the user, such as a smart phone, and a storage of the user of the wearable device included in or communicatively coupled to the wearable device. Because an internal device, as discussed above, is owned by the user, the user has full access privileges and total control over such an internal device. Therefore, the wearable device is provided access to the full functionality of an internal device, while the wearable device's access to an external device is controlled and limited.

In operation 130, the wearable device identifies a predetermined gesture that is mapped to the recognized gesture, and establishes the wireless communication connection with at least one of the external device and the internal device based on the predetermined gesture, as identified. For example, the predetermined gesture corresponds to at least one function that is to be executed in response to the recognized gesture.

In an example embodiment, a gesture of the user where the user moves the wrist from side to side is set to correspond to a communication start function and a communication device setting function, and a gesture of the user moving the wrist up and down is set to correspond to a communication connection setting function. In this example, when the gesture of the user moving the wrist from side to side is recognized based on the sensed motion and biosignal, the wearable device identifies that the communication start function and the communication device setting function are being invoked by mapping the recognized gesture and the predetermined gesture to one another in operation 130. By mapping the recognized gesture and the predetermined gesture to one another, the wearable device is able to establish which function or functions the user intends to invoke with a gesture. Similarly, when the gesture of the user moving his or her wrist up and down is recognized based on the sensed motion and the biosignal, the wearable device may establish the wireless communication connection with at least one of the external device and the internal device, because of the mapping between a user moving his or her wrist up and down and establishing a communication connection.

According to an embodiment, the wearable device identifies, from among a plurality of communication schemes, a communication scheme used to perform wireless communication with at least one of the external device and the internal device, and establishes a wireless communication connection with at least one of the external device and the internal device using the identified communication scheme in operation 130. The plurality of communication schemes may include an NFC scheme, a wireless fidelity (WiFi) communication scheme, an infrared (IR) communication scheme, a cellular communication scheme, such as 3G or 4G, and a Bluetooth communication scheme. The plurality of communication schemes may include a plurality of communication protocols. However, the communication schemes listed are only examples of wireless communication schemes and protocols used to establish a wireless communication connection, and other appropriate wireless communication technologies may be used. Additionally, embodiments do not require that the communication connection be entirely wireless, and in some embodiments a portion of the communication connection between the wearable device and the external device or the internal device may use a wired communication connection.

According to another embodiment, the wearable device identifies data used to perform wireless communication with at least one of the external device and the internal device based on the recognized gesture, and establishes a wireless communication connection with at least one of the external device and the internal device based on the identified data in operation 130. In this embodiment, the data indicates all of the data that may be transmitted and received between the wearable device and at least one of the external device and the internal device. For example, in one use case, when the user makes a payment using the wearable device, the wearable device identifies data to be exchanged with the external device as payment data by recognizing the gesture of the user, and establishes the wireless communication connection with the external device based on the identified data. In this example, payment data may include information such as credit card information providing funds for a purchase transaction.

According to still another embodiment, the wearable device obtains information used for the wireless communication connection from the external device and the internal device based on the recognized gesture, and establishes the wireless communication connection with the external device and the internal device based on the obtained information so as to enable the wireless communication between the external device and the internal device in operation 130.

In an example, the user carries the wearable device and the internal device together on the user's person. Additionally, the user may desire a direct communication between the internal device and the external device. In this example, the wearable device obtains information associated with the external device, information associated with the internal device, and information used to connect the internal device and the external device based on the recognized gesture performed by the user, and establishes the wireless communication connection with the external device and the internal device based on the obtained information.

As an example of the data sharing discussed above, a purchase transaction may take place if the user holds the wearable device in proximity to a tag identifying an item to be purchased, gathers information identifying the item using an appropriate sensor, and then performs a gesture indicating that he or she wishes to purchase that item.

In operation 140, the method performs wireless communication with at least one of the external device and the internal device with which the wireless communication connection is established. When the wireless communication connection between the wearable device and the internal device is established, the wireless communication between the wearable device and the internal device is performed based on settings. For example, the settings may be derived from the interaction between the wearable device and the internal device, as discussed above. Accordingly, the user may use data or settings information stored in the internal device and may further conveniently use the wearable device as part of the execution of a function of the internal device.

The wireless communication between the wearable device and the internal device may be simultaneously conducted during the performance of operations 110 through 130. Accordingly, even if the wearable device includes within itself only a low capacity memory or has low computing power, an embedded memory or a processor of the internal device may be used to supplement the computing resources of the wearable device itself.

According to an embodiment, the wearable device performs wireless communication with the external device and the internal device based on settings of the wireless communication connection, and sets data received from the external device to be stored in the internal device in operation 140. By transferring information from the external device to be stored in the internal device, the information becomes more conveniently accessible for use by the wearable device.

Also in such an embodiment, the wearable device loads data from the internal device, and may perform the wireless communication with the external device based on the loaded data. Here, the loaded data may include information associated with at least one of the user of the wearable device, settings of the wireless communication connection, the wearable device itself, and the internal device itself.

According to an embodiment, the communication method using the wearable device enables a user to perform wireless communication with a user of at least one of an external device and an internal device through feedback, where feedback is information provided by the wearable device in response to input, such as the information discussed above that includes user movement and user biosignals. For example, the communication method using the wearable device may feed back, to the user in a visual, auditory, or tactile manner, information associated with at least one of a function corresponding to an input gesture, the wearable device, the external device, and the internal device. Thus, the feedback is a way for the wearable device to output information that the user may consider when providing further input.

Accordingly, the user, after receiving the feedback, inputs a gesture based on the fed back information. As discussed above, feedback includes visual, auditory, or tactile information. A visual feedback refers to a feedback that is provided using a display included in the wearable device or may refer to a feedback that is provided using a display of the internal device and/or the external device in communication with the wearable device. An auditory feedback refers to a feedback that is provided in a form of sound, such as through a speaker unit of the wearable device or a speaker unit of the internal device or the external device. For example, the speaker unit may be a loudspeaker, but it may also include a group of loudspeakers or speakers that are incorporated into a pair of headphones or a single headphone. A tactile feedback refers to a feedback that is provided in a tactile form, such as through a vibrating unit of the wearable device or a vibrating unit of the internal device or the external device. Feedback is not limited to these examples, and may include any sensory phenomena produced by the wearable device, the internal device, or the external device, or any peripheral of these devices that is able to produce an event that is observable by the user

FIG. 2 illustrates an example of operation 120 of FIG. 1, according to an embodiment.

Referring to FIG. 2, operations 110 and 120 of FIG. 1 are sequentially performed or are simultaneously performed. Accordingly, a case in which operations 110 and 120 are sequentially performed and a case in which operations 110 and 120 are simultaneously performed are separately described.

In the case in which operations 110 and 120 are sequentially performed, in operation 210 the method determines whether to perform wireless communication with the external device. In an example, the wearable device is set to perform the wireless communication with the external device based on the recognized gesture. In this example, the wearable device is set to identify a predetermined gesture that is mapped to the recognized gesture as discussed above, and perform the wireless communication with the external device according to a function corresponding to the predetermined gesture.

In this embodiment, when the wearable device is not set to perform the wireless communication with the external device, the wireless communication with the external device is performed until a subsequent gesture is recognized that indicates that wireless communication with the external device is to be performed.

When the wearable device is set to perform the wireless communication with the external device, at least one external device is searched for in operation 220. For example, the search may be carried out by performing a discovery process that identifies potential external devices with which communication is possible. In this example, the wearable device searches for at least one external device based on a distance between the wearable device and the at least one external device, such as by searching for potential external device within a certain radius. In another example, the wearable device searches for the at least one external device using a list of external devices. However, an embodiment may use any search process that allows the wearable device to establish wireless communication with an external device.

In operation 230, the method selects an external device to perform the wireless communication with the wireless device from among the found at least one external device. For example, the wearable device selects, from among the found at least one external device, the external device to perform the wireless communication based on the recognized gesture. In some example situations, two external devices including a first external device and a second external device are found. In such an example, the wearable device may be set to select the first external device in response to a gesture A input from the user, and to select the second external device in response to a gesture B input from the user. In this example, when the wearable device recognizes the gesture B, the wearable device selects the second external device as the external device to perform the wireless communication.

In the alternative case, in which operations 110 and 120 are simultaneously performed, whether to perform the wireless communication with the external device is determined in operation 210. In this example, the wearable device determines whether to perform the wireless communication with the external device based on predetermined settings, and receives, from the user, settings on whether to perform the wireless communication with the external device.

When the wearable device is set to perform the wireless communication with the external device, at least one external device is searched for in operation 210. In this example, similar to the case in which operations 110 and 120 are sequentially performed, the wearable device searches for at least one external device. Similar to the case in which operations 110 and 120 are sequentially performed, the search may be based on a distance between the wearable device and the at least one external device and may also be based on a search for the at least one external device using a list of external devices.

In operation 230, the method selects the external device to perform the wireless communication with the wireless device from among the found at least one external device. In this example, the wearable device selects, from among the found at least one external device, the external device to perform the wireless communication with the wearable device based on the distance or another criteria used to choose which external device to communicate with. Further, the wearable device may select the external device to perform the wireless communication based on predetermined settings. In one example, the wearable device receives, from the user, settings related to a selection of the external device to perform the wireless communication.

FIG. 3 illustrates a diagram describing an example of a communication method using a wearable device 310, according to an embodiment.

Referring to FIG. 3, in an example the wearable device 310 processes a payment. The payment is processed using a card, such as a credit or debit card, through wireless communication with an external device 320. The external device 320 may be a payment device.

In a case in which a gesture A is set as a gesture to process a payment using a card with the external device 320 as discussed above, the wearable device 310 performs a payment function in response to recognition of the gesture A. For example, when the wearable device 310 is situated to be near to the external device 320, the wearable device 310 recognizes the external device 320 due to proximity. The wearable device 310 may also recognize the external device 320 through gesture recognition. For example, the wearable device 310 may detect a certain gesture and establish which external device 320 to use based on which specific gesture is identified.

During a card payment process, the wearable device 310 identifies card data used to perform the wireless communication with the external device 320 from among a plurality of sets of card data using the gesture recognition. In this example, the plurality of sets of card data may be stored in the wearable device 310 and may also be stored in an internal device (not shown) of, for example, a smart phone, which performs the wireless communication with the wearable device 310. The card data is be stored in the wearable device 310 and/or the internal device because these are devices that belong to the user. Because the user owns the devices, it is appropriate to store private information such as credit or debit card data in these devices, because it is assumed that only the user whose data is stored in the devices will have access to the devices.

When the plurality of sets of card data is stored in the internal device, the wearable device 310 may receive the plurality of sets of card data from the internal device through the wireless communication with the internal device. The wearable device 310 may identify, from among a plurality of communication schemes, a communication scheme used to perform the wireless communication with the external device 320 using the gesture recognition. Example communication schemes have been presented above, and as discussed above any appropriate communication scheme may be used in an appropriate embodiment.

For example, when three sets of card data are stored in the wearable device 310, the wearable device 310 and the external device 320, one embodiment uses three communication schemes, one scheme for each set of card data. That is, a gesture A is set to identify a first set of card data and a first communication scheme, a gesture B is set to identify a second set of card data and a second communication scheme, and a gesture C is set to identify a third set of card data and a third communication scheme. In this example, in response to recognition of the gesture C, the wearable device 310 communicates with the external device 320 using the third communication scheme and may transmit the third set of card data to the external device 320. Through the above procedure, the card payment process is performed.

FIG. 4 illustrates a diagram describing another example of a communication method using a wearable device 410, according to an embodiment.

Referring to FIG. 4, the wearable device 410 performs wireless communication to interact and exchange information with a wearable device 420 of another user.

When the wearable device 410 and the wearable device 420 are positioned in a near field of one another, the wearable device 410 and the wearable device 420 may recognize each other. Alternatively, the wearable device 410 and the wearable device 420 may be able to communicate with each other through another wireless technology, such as Bluetooth. When the wearable device 410 recognizes a gesture set to perform wireless communication with the wearable device 420, the wearable device 410 transmits a wireless communication setting request to the wearable device 420. When the wearable device 420 receives the wireless communication setting request from wearable device 410 and then, recognizes a gesture set by the user of the wearable device 420 to perform the wireless communication with the wearable device 410, a wireless communication connection may be established between the wearable device 410 and the wearable device 420 and data may be exchanged between them. For example, the wearable device 410 and the wearable device 420 may exchange necessary transmissions in order to establish a wireless communication connection.

FIG. 5 illustrates a diagram describing still another example of a communication method using a wearable device 511, according to an embodiment.

Referring to FIG. 5, the wearable device 511 establishes a wireless communication connection to enable wireless communication between an internal device 512 and an external device 513. For example, in FIG. 5, the internal device 512 and the external device 513 are both shown, for purposes of illustration, as smart phones.

Specifically, referring to a block 510, the wearable device 511 obtains information used for a wireless communication connection from the internal device 512 and the external device 513. For example, when the wearable device 511 recognizes a gesture performed by the user using the wearable device 511 as being set to connect the internal device 512 and the external device 513 around the external device 511, the wearable device 511 obtains information used for the wireless communication connection from the internal device 512 and the external device 513 in order to connect the internal device 512 and the external device 513. Information used for the wireless communication connection may include information associated with the internal device 512 and the external device 513 and information associated with a communication right. Such information provides information about the logistics of how to establish the location as well as information that may be used for authentication and security purposes.

For example, when information used for the wireless communication connection is obtained from the internal device 512 and the external device 513, the wearable device 511 controls a connection between the internal device 512 and the external device 513 based on the obtained information so as to enable the wireless communication between the internal device 512 and the external device 513. Accordingly, as illustrated in a block 520, the internal device 512 and the external device 513 directly communicate with each other without using the wearable device 511 once the connection has been established in block 510, as has just been discussed.

According to another example embodiment, in a case in which an external device is a WiFi router, when the wearable device is positioned within a coverage area of the WiFi router, the wearable device recognizes the WiFi router and attempts to establish a communicative connection as discussed above. In this example, when a plurality of WiFi routers is present, several ways of choosing a router are used in various embodiments. In one embodiment, the wearable device selects a WiFi router from among the plurality of WiFi routers based on a recognized gesture. Another embodiment selects a WiFi router from among the plurality of WiFi routers based on predetermined information, and also selects a WiFi router to perform the wireless communication based on a strength of a signal. When the WiFi router is recognized, the wearable device may recognize a gesture and may set the recognized WiFi router to perform the wireless communication with an internal device. To this end, the wearable device obtains a function used for the wireless communication connection from the internal device and the WiFi router, and establishes the wireless communication connection with the internal device and the WiFi router based on the obtained information. Accordingly, the internal device may be directly connected to the WiFi router, without the involvement of the wearable device 511.
